ITS-Tools compared to other tools («Known» models, LTLFireability)
Last Updated
Jun 28, 2020

Introduction

This page presents how ITS-Tools do cope efficiently with the LTLFireability examination face to the other participating tools. In this page, we consider «Known» models.

The next sections will show chart comparing performances in terms of both memory and execution time.The x-axis corresponds to the challenging tool where the y-axes represents ITS-Tools' performances. Thus, points below the diagonal of a chart denote comparisons favorables to the tool while others corresponds to situations where the challenging tool performs better.

You might also find plots out of the range that denote the case were at least one tool could not answer appropriately (error, time-out, could not compute or did not competed).

ITS-Tools versus GreatSPN

Some statistics are displayed below, based on 2036 runs (1018 for ITS-Tools and 1018 for GreatSPN, so there are 1018 plots on each of the two charts). Each execution was allowed 1 hour and 16 GByte of memory. Then performance charts comparing ITS-Tools to GreatSPN are shown (you may click on one graph to enlarge it).

Statistics on the executions
  ITS-Tools GreatSPN Both tools   ITS-Tools GreatSPN
All computed OK 548 29 149   Smallest Memory Footprint
ITS-Tools = GreatSPN 10 Times tool wins 754 175
ITS-Tools > GreatSPN 82   Shortest Execution Time
ITS-Tools < GreatSPN 111 Times tool wins 607 322
Do not compete 0 0 0
Error detected 3 173 0  
Cannot Compute + Time-out 32 381 83


On the chart below, denote cases where the two tools did computed all results without error, denote cases where the two tool did computed the same number of values (but not al values in the examination), denote cases where ITS-Tools computed more values than GreatSPN, denote cases where ITS-Tools computed less values than GreatSPN, denote the cases where at least one tool did not competed, denote the cases where at least one tool computed a bad value and denote the cases where at least one tool stated it could not compute a result or timed-out.

ITS-Tools wins when points are below the diagonal, GreatSPN wins when points are above the diagonal.

ITS-Tools versus ITS-LoLa

Some statistics are displayed below, based on 2036 runs (1018 for ITS-Tools and 1018 for ITS-LoLa, so there are 1018 plots on each of the two charts). Each execution was allowed 1 hour and 16 GByte of memory. Then performance charts comparing ITS-Tools to ITS-LoLa are shown (you may click on one graph to enlarge it).

Statistics on the executions
  ITS-Tools ITS-LoLa Both tools   ITS-Tools ITS-LoLa
All computed OK 3 13 191   Smallest Memory Footprint
ITS-Tools = ITS-LoLa 106 Times tool wins 482 431
ITS-Tools > ITS-LoLa 130   Shortest Execution Time
ITS-Tools < ITS-LoLa 470 Times tool wins 377 536
Do not compete 0 0 0
Error detected 3 3 0  
Cannot Compute + Time-out 10 0 105


On the chart below, denote cases where the two tools did computed all results without error, denote cases where the two tool did computed the same number of values (but not al values in the examination), denote cases where ITS-Tools computed more values than ITS-LoLa, denote cases where ITS-Tools computed less values than ITS-LoLa, denote the cases where at least one tool did not competed, denote the cases where at least one tool computed a bad value and denote the cases where at least one tool stated it could not compute a result or timed-out.

ITS-Tools wins when points are below the diagonal, ITS-LoLa wins when points are above the diagonal.

ITS-Tools versus enPAC

Some statistics are displayed below, based on 2036 runs (1018 for ITS-Tools and 1018 for enPAC, so there are 1018 plots on each of the two charts). Each execution was allowed 1 hour and 16 GByte of memory. Then performance charts comparing ITS-Tools to enPAC are shown (you may click on one graph to enlarge it).

Statistics on the executions
  ITS-Tools enPAC Both tools   ITS-Tools enPAC
All computed OK 130 91 100   Smallest Memory Footprint
ITS-Tools = enPAC 9 Times tool wins 663 328
ITS-Tools > enPAC 156   Shortest Execution Time
ITS-Tools < enPAC 505 Times tool wins 320 671
Do not compete 0 0 0
Error detected 2 133 1  
Cannot Compute + Time-out 105 13 10


On the chart below, denote cases where the two tools did computed all results without error, denote cases where the two tool did computed the same number of values (but not al values in the examination), denote cases where ITS-Tools computed more values than enPAC, denote cases where ITS-Tools computed less values than enPAC, denote the cases where at least one tool did not competed, denote the cases where at least one tool computed a bad value and denote the cases where at least one tool stated it could not compute a result or timed-out.

ITS-Tools wins when points are below the diagonal, enPAC wins when points are above the diagonal.
